Q460D steel plate is a low-alloy high-strength steel plate, and Q460D steel plate is produced according to the standard GB/T1591. The yield strength of Q460D steel plate is not less than 460MPa, the impact temperature of Q460D steel plate is negative 20 impact, and the thickness of Q460D steel plate is 8mm-300mm.
The delivery state of Q460D steel plate is delivered in hot-rolled state. The Q460D steel plate cutting method is laser cutting or flame cutting, and the cutting gap increases according to the thickness of the steel plate.
Mechanical properties of Q460D steel plate:
Yield strength——≥460MPa
Tensile strength - 550MPa-720MPa
Elongation after break——≥18%
Q460D steel plate is easy to cut, process and weld. It has good toughness and high strength. It is often used in cutting metal parts, large gears, or in engineering machinery, metallurgical machinery, mining machinery, and Q460D steel plate can also be used in port ships. Machinery, used in high-rise buildings, bridges and other buildings.
In addition to Q460D steel plates for low alloy grades, there are also different grades such as Q460C steel plates or Q355D steel plates, Q420D steel plates of the same grade with slightly lower strength, and Q460ND steel plates, Q460NC steel plates, Q355ND steel plates, Q355NE steel plate, Q420D steel plate, Q420ND steel plate, Q420NC steel plate, etc.
